COMBINED TENONING AND MORTISING MACHINE.

SPECIFICATION forming part of Letters Patent No. 366,822, dated July 19, 1887.

Application filed October 2, 1886. Serial No. 215,152.

State of Kansas, have invented a new and In1- proved Combined Mortising and Tenoning Machine, ofwhich the following is a full, clear, and exact description.

My invention relates to a foot-power mortising and tenoning machine; and the invert tion consists, principally, in a practicable CODI' bination of the two machines.

The invention also consists in the feed mech' anism, and in the means for holding and placing the cutters.

The invention also consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of my combined mortising and tcnoning machine. Fig. 2 is a sectional elevation of the same, taken on the line as a: of Fig. 1. Fig. 3 is a detailed sectional plan view taken on the line 9 y of Fig. 2, and Fig. shows one of the tcnoning'knives.

A represents the upright frame of the machine supported upon the base A and legs A and constructed to form the ways 13 B, in which the frame 0 is vertically reeiprocated for causing the mortisingknife a and tenoning-knives Z) I), carried thereby, to perform their work. The mortising-knife a is not can ried directly by the frame 0, but is held in a cylindrical stock, D, held in the sleeve D, made a part of the plate D", which is attached to the upper end ofthe frame 0 by a bolt, D which passes through a slotin the plate D", so that the plate may be adjusted back and forth upon the frame C by the screw D, to change the position of the knife a, as the work may require. The stock D is adapted to be turned in the tube D by the handled, for turning the knife a to cut both sides and ends of the mortise.

The knives b Z) are secured by cleats and screws, or other obvious means, to projections c c of the side pieces, 0 c, of the frame 0, and are each formed with a diagonal cutting-edge, b, as shown in Fig. 4, to cut and remove the (No model.)

timber T upon both sides to form the tenon 1. (Shown clearly in Fig. 3.) The frame 0 is vertically reciprocated, to cause the knives b and a to do their work, by means of the treadle E, connected to the frame by the connecting rod E and the connected springs E and E, the former connected to the frame O by the projection 0 the latter held stationary upon the studs 0" c, attached to the main frame A.

The timber T to be worked is supported upon a table, F, held to the front of the main frame A by the heavy bolt F, passed through thetable and through the cleat F at the back of the frame A, so that by loosening the nut upon this bolt the table maybe raised or lowered according to the width of the timber to be worked.

G represents a holding and feed frame for holding and feeding the timber to the knives. This is attached to the table F by a bolt, G", passed through the horizontal board G, attached to the lower edge of the frame G, as shown clearly in Figs. 1. and 3. \Vit-hin the frame G is held the sliding feedplate G", which is provided with a bent arm, g, and clampserew g, for clamping the piece of timber T to the front surface of the feed-plate G, as shown clearly in Fig. 1. The plate G" is adapted to be moved longitudinally in the frame G, for feeding the timber to and from the knives, by the screw ]T, which works in aserew-thrcadcd opening made in the outer bar, g, of the frame G, and passes through a screw-threaded opening in a elcat, h, attached to the feed-plate, as shown clearly in Fig. 3.

'Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The vertically-sliding frame C, carrying the block D", and screw D, for adj usting the block D" horizontally,and the knife-stock 1), held in the sleeve D of the block D", in combination with the table F, frame G, horizontal sliding plate G, provided with the clamp g and screw 9, and the tenoning-knives I), attached to opposite sides of the frame O, substzmtially as described.
